Relationship Math...

If I were to run a regression- what would be the statistical significance? Any omitted variable bias?

a great friendship + emotional connection x exclusive sex a few times a week if you’re lucky or month = a “relationship”

I'm just curious because if this explains more than 80% of the variation in relationship data then I'm somehow missing something... besides the obvious someone.
